AR-57 Upper For AR15 Rifles, 5.7FN

This highly anticipated upper is a direct replacement for your standard AR upper that will allow you to shoot the FNH 5.7 round. This upper requires no FFL to purchase or receive, and we can ship directly to your home!

The AR-57 platform empowers the operator with 50 rounds of firepower while keeping the magazine out of the way, increasing maneuverability and speed in close quarters conflicts. In addition to it's compact, snag-free design, the spent shells are directed straight towards the floor by exiting the standard AR magwell.

The upper receiver and rails are precisely milled from a monolithic block of aircraft grade 7075 T6 aluminum. Any sighting systems mounted on the rails will stay zeroed through the toughest of missions.

Designed with reliability as its primary feature. There is no gas system to become clogged with carbon or fouling and maintenance is a snap. The bolt and chamber stay clean through extended shooting sessions.

This new offering defines "High speed, low drag".

Included is the upper only. Red dot scope not included. The magazine pictured in the mag well is not included. This is our ''brass catcher''. (it's just a hollowed out AR15 mag- and yes- you saw it here first!) The brass is ejected out the botttom of the mag well, you do not need a mag for the upper to function.

Take caution in buying this upper,
February 02, 2015

Beware of this upper, there are serious design flaws built into this firearm. This upper will fire with the bolt not fully closed. I've made AR57 aware of this, I have an upper that did just that, or I should say the pieces of an upper. AR57 said they would replace the upper(don't know if I want a replacement given the defect). It doesn't look like this will be an issue as they said they shipped a replacement 3 times, I have yet to see said replacement and now they will not answer or return any of my calls. Save your money and look at a different upper, this one is not worth your time or fingers!
